Testimonials

We needed a special part made for one of our biggest customers that none of our other suppliers would even quote. Superior not only quoted the part but custom manufactured it in less than 6 weeks and they were PERFECT! - Collin T.

I tried for years to get in the door with a major manufacturer in my territory but I kept losing out on price. I had Superior quote the same items my other suppliers were quoting and now I’m the primary supplier to the OEM. Superior’s price and quality are excellent. - Jimmy S.

I needed 19 pieces of a 2" A449 23" long shipped ASAP. I found only 2 suppliers in the US who had the parts in stock but only Superior could ship the same day and they were 62% less expensive than the other supplier. - Alex P.

I was a little concerned because the price I was quoted from Superior was less than ½ that from my other supplier. John assured me the quality would be excellent so I took a chance. He was right. My customer loved the parts and the savings. - Marty N.
